THERMAL TRANSFER SHEET

A thermal transfer sheet, which includes a transfer layer, is superposed on a transfer receiving article, and while the transfer layer is continuously transferred onto the article by a printer comprising a sheet supplying device, heating device, sheet winding device, measuring device located between the heating and sheet winding devices to measure the tensile strength of the thermal transfer sheet conveyed along a conveyance path, and release device located between the heating and the measuring devices, under conditions including an applied power for printing: 0.15 W/dot and a conveying speed for the thermal transfer sheet: 84.6 mm/sec., the transfer layer transferred on the article is released from a constituent member in contact with the transfer layer of the thermal transfer sheet, has a tensile strength measured by the measuring device of 0.1 N/cm or less.
